Separated from the embassy by Chinese police, protesters joined in chants such as “Malaysian government has cheated us” while holding signs that read “We want our families. We want the truth.”

The Chinese government is also playing skeptical. China’s Deputy Foreign Minister Xie Hangsheng Monday demanded all of Malaysia’s relevant data analysis from satellites on how the country came to their conclusions. On Tuesday, China’s foreign ministry said it hoped that Britain would provide the data from British satellite telecommunications company Inmarsat, whose data Prime Minister Razak cited when claiming the plane had crashed.
